SRX1500 Services Gateway Clearance Requirements for Airflow and Hardware
Maintenance
When planning the installation site for the SRX1500 Services Gateway, you need to allow
sufficient clearance around the rack. Consider the following:
•
For the cooling system to function properly, the airflow around the chassis must be
unrestricted. The fan tray contains four fans and provides front-to-back chassis cooling.
Figure 6 on page 27 shows the direction of airflow through the chassis.
•
For service personnel to remove and install hardware components, there must be
adequate space at the front and back of the services gateway as indicated in
Table 10 on page 26 .
• If you are mounting the services gateway in a rack with other equipment, ensure that
the exhaust from other equipment does not blow into the intake vents of the chassis.
Table 10 on page 26 provides information about the clearance requirements for
maintaining optimum airflow and the distances necessary to facilitate easy maintenance
of the services gateway.

Requirement for Clearance
Recommended
Clearance
Location
Space for service personnel to remove
and install hardware components 8.7 in. (22 cm) Front of the chassis
Space for service personnel to remove
and install hardware components 17.4 in. (44.2 cm) Rear of the chassis
Space for cable management and
organization 2.5 in. (6.35 cm) Between front-mounting flange
and rack or cabinet edge

function properly and to maintain
unrestricted airflow around the chassis 6.0 in. (15.24 cm) Between both sides of the
chassis and any
non-heat-producing surface
such as a wall or cabinet side
